Unique 3D map of the universe created

Ontario, April 28 ,2015: Astrophysicists have created a 3D map of the universe that spans nearly two billion light years and is the most complete picture of our cosmic neighbourhood so far.

The spherical map of galaxy superclusters will lead to a greater understanding of how matter is distributed in the universe and provide key insights into the mysterious dark matter, the researchers noted.

The galaxy distribution is not uniform and has no pattern.

"It has peaks and valleys much like a mountain range. This is what, we expect if the large-scale structure originates from quantum fluctuations in the early universe," explained professor Mike Hudson from University of Waterloo.

The lighter blue and white areas on the map represent greater concentrations of galaxies.

The red area is the supercluster called the "Shapley Concentration", the largest collection of galaxies in the nearby universe.

Unexplored areas appear in medium blue.

"Knowing the location and motion of matter in the universe will help astrophysicists predict the universe's expansion and identify where and how much dark matter exists," Hudson explained.
